Move "select all" on incoming exchanges to a server call

[luisramos0]

What we should change and why (this is tech debt)

We can now avoid having to load all products to the browser in most situations by making the select all button call the server instead of loading all products and then select them all.

Context

This is a natural improvement after #4476, this was not done as part of #4471 to keep that PR small.

Impact and timeline

This will have a massive impact when handling very large OCs. With this change, we can probably load the incoming exchange, select all products and save in under 1 minute even for a 10k products exchange.
